The neural crest is regionalized along the anteroposterior axis, as demonstrated by
foundational lineage-tracing experiments that showed the restricted developmental potential …

The ability to continuously grow and regenerate the gills throughout life is a remarkable
property of fish and amphibians. Considering that gill regeneration was first described over …

Classification of the tremendous diversity of ray-finned fishes (Actinopterygii) began with the
designation of taxonomic groups on the basis of morphological similarity. Starting in the late …

Estrogenic compounds including 17β estradiol (or E2) are known to negatively affect the
reproductive system of many animals, including fish, leading to feminization, altered sex …

In the last decade, the CRISPR/Cas9 bacterial virus defense system has been adapted as a
user-friendly, efficient, and precise method for targeted mutagenesis in eukaryotes. Though …

Whereas the gill chambers of jawless vertebrates open directly into the environment, jawed
vertebrates evolved skeletal appendages that drive oxygenated water unidirectionally over …

Our understanding of the evolutionary origin of Chordata, one of the most disparate and
ecologically significant animal phyla, is hindered by a lack of unambiguous stem-group …

The cranial neural crest (CNC) arises within the developing central nervous system, but then
migrates away from the neural tube in three consecutive streams termed mandibular, hyoid …

The vertebrate pharynx is a key embryonic structure with crucial importance for the
metameric organization of the head and face. The pharynx is primarily built upon …

Of all the cell types arising from the neural crest, ectomesenchyme is likely the most unusual.
In contrast to the neuroglial cells generated by neural crest throughout the embryo …
